  • Publication number: 20200248468
    Abstract: A rebar tying machine wire feeding disc braking mechanism with positioning device has a braking part for stopping a wire feeding disc and a cam mechanism for controlling actions of the braking part. The cam mechanism has a cam and a push shaft mounted on a fixed seat, capable of axial displacement. One end of the push shaft presses against a rim of the cam and reciprocates along with the changing outline of the rim. A middle portion of the push shaft is a diameter-varying segment and presses against one end of the braking part such that the braking part swings forwards and backwards with the translation of the push shaft, the cam mechanism realizes stopping through the positioning device. The forward rotation inertia of the cam is eliminated such that the cam is stopped.

  • Patent number: 10654795
    Abstract: A method for synthesizing a ketoxime is provided. In a system of an aqueous carbonate solution, a reaction is performed on a ketone, ammonia and hydrogen peroxide by using a titanium-silicon molecular sieve as a catalyst to obtain the ketoxime. Moreover, a reaction progress is judged and an optimal reaction ratio is determined by a real-time monitoring of a pH value in a reaction system during the reaction. In the present invention, by monitoring the pH value in the reaction system, the progress of the reaction is judged, thereby determining the optimal reaction ratio. The pH of the system is further adjusted by an aqueous carbonate solution to increase the reaction velocity and conversion rate of the ammonia.

  • Publication number: 20160066568
    Abstract: The present invention relates to packaging material/matrix and methods of making such packaging material/matrix for slow or extended release of at least one active volatile compound(s). Provided are methods and compositions for a polymer matrix incorporating at least one active volatile compound (for example 1-methylcyclopropene or 1-MCP) and the polymer matrix is synthesized by polycondensation. This polymer matrix can slowly release the active volatile compound after contacting with a solvent (for example moisture). Also provided is the use of such polymer matrix to prolong the shelf-life of fruits and vegetables.
